I can't quite see it, I think I'm going to need to see some more pictures...
I agree. I'd like to see a close up picture of those spools with the covered protectors off. I always like to hold the spools in my hand to see if they are soft or hard. I've found that hard spools are usually filled with silicone that has gone bad. I like my spools soft with a large capacity. It looks like you have different models of spools in the pictures. Please give close up of each model so I can make up my mind. I'm very particular about my spools. Thanks.
